Overview

FemtoClock® NG Clock Synthesizer 843N571I Datasheet Description The 843N571I is a PLL based clock synthesizer for use in Ethernet applications.
The device uses IDT’s fourth generation FemtoClock® NG technology for optimal high clock frequency and low phase noise performance, combined with a low power consumption and high power supply noise rejection.
Using IDT’s latest FemtoClock NG PLL technology, the 843N571I achieves <0.
3ps RMS phase jitter performance.
843N571I can synthesize 100MHz, 125MHz, 156.
25MHz and a low frequency 33.
33MHz CPU clock from a single device.
Six LVCMOS outputs also serve as additional buffering of the 25MHz crystal reference.
Features • Fourth generation FemtoClock® Next Generation (NG) technology • Seven single-ended LVCMOS outputs, 30 output impedance • Three LVPECL output pairs One differential LVPECL (QA, nQA) output pair: 156.
25MHz Two selectable differential LVPECL output pairs (QB, nQB and QC, nQC): 100MHz and 125MHz • One single-ende...
